In the Flow Rate Experiment, young scholars perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab (accessible through TeachEngineering.com) to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, young scholars hypothesize about the flow rate in a nearby river, and then use the Engineering Our Water Living Lab to check their hypothesis. For this lesson to be effective, your students need to have a visual feel for the flow in a nearby river.
